SHOE-POLISHING MACHINE.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed August 1,1906. Serial No. 328.783

To all whom it may concern:

Be it known that I, JOHN A. BREWER, a citizen of the United States,residing at Jackson, in the county of Jackson and State of Michigan,have invented new and useful Improvements in Shoe-Polishing Machines, ofwhich the following is a specification.

This invention relates to that class of shoe polishing machines in whichthe operating mechanism is set in motion by the dropping of a coin andit has for its object to simplify and improve the construction andoperation of this class of'machines.

With this and other ends in view which will readily appear as the natureof the invention is better understood, the same consists in the improvedconstruction and novel arrangement and combination of parts which willbe hereinafter fully described and particularly pointed out in theclaims.

In the accompanying drawings is illustrated a simple and preferred formof the invention; it being however, understood that no limitation isnecessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theinvention may be resorted to when desired.

In the drawings: Figure l is a front elevation, partly in section, of amachine embodying the invention. Fig. 2 is a vertical sectional View ofthe upper portion of the machine. Fig. 3 is a vertical transversesectional view taken on the plane indicated by the line 33 in Fig. 2.Fig. 4 is a diagram illustrating the movement of the belt whereby theshoe polishing devices are operated. Fig. 5 is a diagram illustratingthe electrical circuit including the motor whereby the machine isoperated. I 7

Corresponding parts in the several figures are denoted by likecharacters of reference.

A suitable casing is provided having a bottom compartment 1 and an uppercompartment 2. A tubular standard 4 rising from the casing is incommunication with the bottom compartment of the latter, and saidstandard supports at its upper end an auxiliary casing 5; the latterbeing connected with the tubular standard 4 by means of braces 6 whichconstitute handles adapted to be grasped by the person using the machinewho may thus support himself in a convenient position.

The partition 7 which separates the bottom compart ment 1 from the uppercompartment 2 is provided with bearings for shafts 8, 9 one of whichcarries a brush 10 and the other a buffer or polisher 11 which lattermay be composed of pieces of felt or textile material so arranged thattheir edges shall constitute the working face of the polisher. Thelatter as well as the brush is preferably of an inverted conical orfrustum shape illustrated in the drawings, although they are notnecessarily limited to this shape. The shafts S and 9 are provided neartheir lower ends with grooved pulleys 12 and 13 for the passage of thebelt 14 whereby they are driven. Within the compartment 1 of the casingis mounted an electric motor 15 the shaft of which 16 carries a groovedpulley 17 the belt 14 is guided over the pulleys 12, 13, 17 and over apair of guide pulleys 18, 19 which are suitably supported below thepartition 7 so that, when the motor is in operation, rotary motion willbe transmitted to the brush and the polisher.

The shaft 16 of the motor has a worm 20 meshing with a worm gear 21 uponthe lower end of the shaft 22 which latter extends vertically throughthe tubular standard 4 into the auxiliary casing 5; the latter isprovided with bearings for a horizontally disposed shaft 23 whichprojects at one end through the casing and carries a hand or pointer 24that moves over a dial 25; the shafts 22 and 23 are provided withintermeshing bevel gear 26, 27.

The auxiliary casing 5 is provided with a coin chute 28 terminatingadjacent to a pair of plates 29 which are suitably spaced apart, saidplates being constructed of glass or similar nonconducting material.Adjacent to the plates 29 are binding posts 30, 31 with which areconnected springs 32, 33 that extend between the plates 29 in thedirection of each other so that said springs together with the plates 29will constitute an extension or continuation of the coin chute. Thespring 32 is extended below the plates 29 as will be clearly seen at 34in Figs. 2 and 3 of the drawings. Connected with the binding post 31 isan additional spring 35 which is inclined downward adjacent to one ofthe plates 29; said spring being extended beyond the extension 34 of thespring 32. The springs 32, 33 and 35 constitute electrical conductors;and a shaft 22 is provided with a radial arm 36 adjacent to the loweredges of the plates 29 said arm being adapted to engage the lower end ofthe spring 35 and the extended end 34 of the spring 32.

The binding post 30 is connected by a conductor 37 with one pole of themotor 15; the other pole of said motor being connected with the sourceof power by a conductor 38. A conductor 39 connects the source of powerwith the binding post 31 as will be best seen by reference to thediagram in Fig. 5 of the drawings.

When the coin is dropped through the chute 28 it will be caught betweenthe springs 32, 33, and will thus complete an electrical circuit wherebythe motor 15 will be set in motion. The user of the machine, steadyinghimself by the handles, applies his feet in succession to the brush 10and the polisher 11. The motor serves to rotate the shaft 22 the arm 36of which will presently pass into engagement with the projecting end 34of the spring 32 which, latter will thus re lease the coin and permitthe latter to drop; the circuit will however remain unbroken until thearm 36 passes out of engagement with the spring 35 which projects beyondthe extended end of the spring 32, so that the latter will be releasedfrom the arm 36 before the motion ceases; said spring 32 will thus berestored to normal position for engagement with the next coin that maybe introduced into the box.

It will be seen that the shaft 22 Will make a complete revolution forevery coin introduced into the de- Vice; and the pointer 24 is intendedto make a complete circuit of the dial 25 simultaneously therewith, thusenabling the user of the machine to properly gage the amount of Workbestowed upon each shoe.

The improved device is simple in construction, and it has proven to bethoroughly eflicient in practical operation.

Having thus described the invention what is claimed is:

A shoe polishing machine comprising a casing having a horizontalpartition therein, an upright standard secured to said casing, anauxiliary casing at the top of said standard, shafts journaled in saidpartition, frusto-conical polishing'and cleaning brushes secured to saidshafts, a motor in said casing, a worth on the motor shaft, a verticalshaft extending through said standard and operatively conn'ected withthe worm on the motor shaft, a pulley on the motor shaft, a pulley oneach of the brush shafts, pulleys supported under the partition, a beltpassing around said pulleys, means for starting said motor and rotatingsaid brushes, and means on said vertical shaft for automaticallystopping the rotation of said brushes, after a predetermined lapse oftime.

In testimony whereof, I affix my signature in presence of two witnesses.

JOHN A. BREWER.
